2. The correct answer is (B).

This question is really asking�you to calculate�the total volume used. This is the total volume of a dose times the number of doses, which is then expressed in milliliters:

Biology

1. The correct answer is (C). Glomerular filtration is the process by which the kidney removes most of the waste products from the blood by pure filtration through the glomerular membrane. Hydrogen ions undergo tubular secretion into the glomerular filtrate, whereas substances such as glucose, amino acids, and potassium ions are actively reabsorbed by the tubular membrane. Sublimation is a physical change from the solid directly to the gaseous state, and does not apply to the kidney or any other organ.

2. The correct answer is (C). The rods of the retina are responsible for peripheral, achromatic, and poor detail vision. Central, color, and detail vision are functions of the cones of the retina.

Chemistry

1. The correct answer is (A). Rayon, nylon, and orlon are all synthetic fibers. Nylon is a synthetic protein, orlon is a polyester fiber, and rayon is regenerated cellulose. However, cellulose is an organic fiber; it is not synthetic.

2. The correct answer is (C). The angstrom (A�) is 1 � 10^-10 m, or 1 � 10^-8 cm, the average radius of an atom.

Reading Comprehension

1. The correct answer is (B). See the first sentence of paragraph one.

2. The correct answer is (C). See the first sentence of paragraph two.

Reading Comprehension

Adrenergic agents, commonly found in appetite suppressants, bronchodilators, central nervous system stimulants, and vasoconstrictors, produce slight pupillary dilation. They have not been observed to produce any adverse effects in open-angle glaucoma, and the incidence of deleterious effects on angle closure glaucoma after systemic administration has been extremely low. Adrenergic agents such as epinephrine and phenylephrine have been used ocularly to treat open-angle glaucoma. It is important to note, however, that these agents will elevate the intraocular pressure by narrowing the anterior chamber angle when instilled into eyes of angle closure patients.�

General anesthetics producing parasympathetic and sympathetic imbalance may cause pupillary block. To prevent this complication, topical pilocarpine at 1% may be instilled into the eye one hour prior to anesthesia.1. Adrenergic agents are commonly found in all of the following EXCEPT:
(A) bronchodilators.
(B) bronchoconstrictors.
(C) vasoconstrictors.
(D) appetite suppressants.

2. General anesthetics that produce parasympathetic and sympathetic imbalance may cause:
(A) pupillary constriction.
(B) pupillary dilation.
(C) pupillary block.
(D) pupillary stimulation.

When you take the PCAT, you must bring your admission ticket and two forms of ID. This policy is strictly enforced.
